A suitable high gain 70cms antenna for SOTA operation was sought that did not have the drawbacks of a long Yagi antenna, principally a narrow beamwidth and bandwidth.

An ingenious portable satellite antenna designed for the IC-705. Addressing its lack of full duplex, the IC-705’s Split Mode enables FM satellite communication, with memory channels programmed for Doppler correction. The antenna combines a 2m Moxon and 70cm Yagi for mechanical simplicity and a single feed point, ideal for handheld use. Built with 3D-printed parts, TIG welding rods, and PVC pipe, it’s lightweight, transportable, and effective. STL files and detailed instructions ensure easy replication for enthusiasts.
